Google Pixel smartphones save "motion photos" in a special format based on a regular JPEG image but also containing a short video sequence. These motion photos can be opened using Windows Photo Viewer. Once opened, it displays "motion."
It's a JPEG + embedded MP4 video.
The MP4 is embedded in the JPEG's XMP metadata or directly in the file container.
I'm looking for a way to select and save individual photos myself.
Maybe Hert is reading this and can answer whether this is available or planned for the future

Best,
Ralf
